## Abstract A new aromatic diamine monomer containing benzoxazole substituents was prepared by a multistep synthesis starting from 1,4βdibromoβ2,5βdifluorobenzene. The diamine was polymerized with commercial aromatic dianhydride or dicarboxylic acid chloride monomers to provide several different po

## SYNOPSIS 3,5-Dinitrobenzoyl chloride reacted with various alcohols such as phenol, biphenyl-4-01,lnaphthol, or diphenylmethanol to afford the 3,5-dinitrobenzoic acid ester derivatives which were catalytically hydrogenated to the corresponding diamines. The latter reacted with terephthaloyl dich
Poly(ethylene terephthalate)-co-poly(ethylene DDP)s [PET-co-poly(ethylene DDP)s], were synthesized by charging 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOP), itaconic acid, terephthalic acid, and ethylene glycol in one reactor to conduct the microaddition reaction (using H 2 PtCl 6 as cat
